Description

Help keep your work van planted over every load with the KYB shock absorber, MPN 554348 — a Gas-a-just high-pressure monotube gas shock built for the rear position. It fits many vehicles as a direct-fit replacement for the listed applications, among them the 2003-2025 Chevrolet Express 2500, 2006-2025 Chevrolet Express 3500 and 2003-2025 GMC Savana 2500. See the "Vehicles it fits" section for the full list and engine-level detail.

High-pressure monotube design: separates the gas and oil for fade-free operation and instant response.
Triple chrome plated piston rod: ultra-smooth to reduce seal wear, since fluid leaking can be a cause of shock failure.
Higher gas pressure: the KYB Gas-a-just responds quickly to help improve steering response.
Built for GM vans: components and valving designed specifically for these vans, adding up to 25% more damping over original-equipment shocks for vehicles that work, tow, and run larger, heavier tires and wheels — and helping keep Electronic Safety Systems performing as designed.

Unlike a traditional twin-tube, this Gas-a-just runs an air-free hydraulic piston/valve chamber for control plus a separate high-pressure nitrogen chamber with a floating piston for a comfortable ride during normal driving.

Is this a front or rear shock?

It is cataloged for the rear position on the listed applications.

What is the benefit of the monotube design?

Is the KYB shock absorber price for one shock or a pair?

This listing is for one shock, sold individually. For even, balanced ride control, replacing both rear shocks together as a matched pair is recommended.
